Amaravati, March 17, 2026: Coastal erosion threatens nearly 34% of India's 7,500-km shoreline, with Andhra Pradesh's Vizag coast facing repeated damage from waves, cyclones, and rising seas.
Institute Chair Professor Neelima Satyam D. from IIT Indore highlights Microbially Induced Calcite Precipitation (MICP), a technique that uses urease-producing bacteria like Sporosarcina pasteurii to bind loose coastal sand into stronger, sandstone-like material in weeks.
Lab tests show the eco-friendly process boosts sand durability against rain and wave erosion far better than costly hard structures like seawalls. It avoids disrupting natural ecosystems unlike traditional fixes.
